About this study
Official title: Pharmacokinetic-pharmacodynamic Interaction Between Three Different Single Doses of BIA 3-202 and a Single Dose of Controlled-release 200/50 mg Levodopa/Carbidopa (Sinemet® cr 200/50): a Double-blind, Randomised, Four-way Crossover, Placebo-controlled Study in Healthy Volunteers
The purpose of this study is to the effect of three single oral doses of nebicapone (50 mg, 100 mg and 200 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa 200 mg/carbidopa 50 mg (Sinemet CR 200/50).
Read the detailed description
Single centre, double-blind, randomised, placebo-controlled, 4-way crossover study with four single-dose treatment periods. The washout period between doses was 5 days or more.
Procedures:
Screening: Subjects will be screened for eligibility within 28 and 7 days of first admission. Written informed consent will be obtained before any study procedure is performed. The screening will consist of: medical history; physical examination, vital signs; complete neurological examination; 12-lead ECG; hematology, coagulation, plasma biochemistry and urinalysis tests; HIV, hepatitis B and hepatitis C serology; drugs of abuse and alcohol screen; urine pregnancy test in women of childbearing potential; and review of the selection criteria. The results of screening must be known to the investigator prior to the subject's first admission.
Treatment periods: In each of the four consecutive treatment periods, eligible subjects will be admitted to the UFH on the day prior to receiving the study medication for: vital signs; medical history and physical examination updates; 12-lead ECG; hematology and plasma biochemistry; drugs of abuse and alcohol screen; and urine pregnancy test in women of childbearing potential. On the first admission the subjects will have a review of the selection criteria and will be randomized to one of the treatment sequences. On the morning of the dosing day, subjects will receive a dose of BIA 3-202 / Placebo concomitantly with a dose of Sinemet CR 200/50 in fasting conditions (at least 8 hours) and will remain in the UFH until at least 24 h post-dose; then, they will be discharged and will return for the next period or the follow-up visit. At given time-points between pre-dose and discharge, subjects will be submitted to vital signs recording, brief neurological examinations, 12-lead ECG, and blood sampling for plasma drug assays and erythrocyte S-COMT activity. At discharge, vital signs and ECG will be recorded, and hematology and plasma biochemistry tests will be performed.
Follow-up: A follow-up visit will occur approximately 7-10 days after discharge of the last treatment period or early discontinuation for: medical history and physical examination updates; vital signs; 12-lead ECG; hematology, plasma biochemistry and urinalysis tests; and pregnancy test in women of childbearing potential.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to the effect of three single oral doses of nebicapone (50 mg, 100 mg and 200 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa 200 mg/carbidopa 50 mg (Sinemet CR 200/50).
Detailed description
Single centre, double-blind, randomised, placebo-controlled, 4-way crossover study with four single-dose treatment periods. The washout period between doses was 5 days or more.
Procedures:
Screening: Subjects will be screened for eligibility within 28 and 7 days of first admission. Written informed consent will be obtained before any study procedure is performed. The screening will consist of: medical history; physical examination, vital signs; complete neurological examination; 12-lead ECG; hematology, coagulation, plasma biochemistry and urinalysis tests; HIV, hepatitis B and hepatitis C serology; drugs of abuse and alcohol screen; urine pregnancy test in women of childbearing potential; and review of the selection criteria. The results of screening must be known to the investigator prior to the subject's first admission.
Treatment periods: In each of the four consecutive treatment periods, eligible subjects will be admitted to the UFH on the day prior to receiving the study medication for: vital signs; medical history and physical examination updates; 12-lead ECG; hematology and plasma biochemistry; drugs of abuse and alcohol screen; and urine pregnancy test in women of childbearing potential. On the first admission the subjects will have a review of the selection criteria and will be randomized to one of the treatment sequences. On the morning of the dosing day, subjects will receive a dose of BIA 3-202 / Placebo concomitantly with a dose of Sinemet CR 200/50 in fasting conditions (at least 8 hours) and will remain in the UFH until at least 24 h post-dose; then, they will be discharged and will return for the next period or the follow-up visit. At given time-points between pre-dose and discharge, subjects will be submitted to vital signs recording, brief neurological examinations, 12-lead ECG, and blood sampling for plasma drug assays and erythrocyte S-COMT activity. At discharge, vital signs and ECG will be recorded, and hematology and plasma biochemistry tests will be performed.
Follow-up: A follow-up visit will occur approximately 7-10 days after discharge of the last treatment period or early discontinuation for: medical history and physical examination updates; vital signs; 12-lead ECG; hematology, plasma biochemistry and urinalysis tests; and pregnancy test in women of childbearing potential.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing BIA 3-202 and Sinemet® in people with Parkinson's Disease, run by Bial - Portela C S.A. at 1 site in Portugal.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 May 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Portugal. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cmax (time frame: pre-dose, ½, 1, 1½, 2, 3, 4, 6, 8, 12, 16 and 24 hours post-dose.). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2016.
